Below is a link to an article looking into strength training for older adults published by Fitness Australia.
Summary:
This review showed that training duration is the most important factor for gains in muscle strength among older adults. Older clients should be made aware that to gain and maintain muscle strength, ST needs to become a part of their weekly routine. The current physical activity guidelines recommend that older adults should do at least two ST (strength training) sessions every week (www.health.gov.au).
Dont forget the use of resistance bands and body weight work undertaken in class and private sessions will constitute strength gains.
Hope you enjoy the read, let me know if you have any questions…..
